Final answer:
The passage does not explicitly mention that Christina felt badly about how she had treated her mother, but we can infer her feelings from the sentence, "That night, Caitlin crawled into a strange bed, wishing she had not come." This sentence suggests that Caitlin regrets her decision to visit Maria and feels unhappy about the situation she finds herself in.
